IMPROVD TUMLR-WASH-ER.

Be it known that I, JOSEPH l. MILBRN; ot Washington, in the county of Washington, and District ot' Columbia, have invented certain new and useful Improvements in Tumbler-Washerspand I hereby declare the `followingA to'bc a full, clear, and exact description of the same, reference beinghad to the accompanying drawings. y

My invention has reference to apparatus employed in'connection with soda-fountains, or in restaurants, or other places where it is .essential to have the means always at hand for washing tumblers, glasses, or other like articles speedily and thoroughly; and it consists essentially of-' I.

AFirst, the'combination of an upright water-tube, upon which the tumbler is.` supported, of an annular vwater-tube, or-a series of tubes surrounding the tumbler, and a valve-mechanism, substantially as `hereinafter describecLAso that, -when the tumbler is placed over or upon its supporting-tube, it will be washed both externally and internally.

Second, the arrangement of the nozzles 1or orifices through which water is discharged upon the exterior of the tumbler, in the manner hereinafter described, so that the `jets of water shall be discharged tangentially or thereabouts to the tumbler. i i

Third, the combination, with the annular or exterior pipe or pipes, of set-screws or cocks, or equivalent mechanism for regulating the'tlow and pressure of water in said'pipev or pipes.

To enable others skilled in the art to understand and use my invention, I-will now proceed'to describe the manner in which the siamois or may be carried into effect by reference to the accompanying drawings, in which- Figure 1 'is a perspective view of Aa tumbler-washing-apparatus made in accordance with my invention.

VFigure 2 is a vertical central section of the same.

Contining attention to that portion of the apparatus upon which the tumbler is placed,vand from which water is discharged into the interior of the tumbler, it will be seen that it consists of an upright pipe or tube, A, connected with the main water-pipe B by a, joint or box, C,.which cnstitutes a chamber in which the valve for regulating the iiow of water is contained. Within the pipe is a valve-rod or stem, a, which extends down -through' the pipe, and has'formed on or attached to its lower end the valve b, which is located -in the' chamber C.

The upper partof the valve is conical, while its lower portion is cylindrical, as. shown clearly in fig. 2. The

size of the valve is such that, whenlraised and pressed 'against vits seat in the lower end of the` pipe A, as india cated in red lines,.g. 2, its lower and cylindrical portion will clos'e'the orifice c in the box C, through which the watcrfrom the pipe B enters. -When, on thi; contrary, the `v alve is depressed, as represented in black lines in the same gure,`the water, onaccount` of the bevelled or conical formationof'the upper part of the valve, is

' free to enter through the orifice c and pass up through the pipe A. The upper end of the valveerd a, when the valve is'closed, rises some distance above the open top of the pipeA, and this end of the rod has formed upon it a series of longitudinal ribs, nl, which t in the pipe and serve to steady the valve-rod. The spaces or intervals between the ribs ailord ample opportunity for the water to passout from the pipe when the valve is depressed.

The valve, thus arranged, is held up against its seat, as indicated-in red lines, fig. 2, by the pressure'of.

the water in the pipe B. For instance, when the valve is depressed by the weight 'of thetumblei D placedon its upper end,ithe water will pass through the orifice e-up through the pipe A, from the upper end of -whichit will be forcibly discharged into the tumbler, the interior 'of which will be thoroughly washed and cleaned; When, after being cleaned, the tumbler is removed, the, impetus of the water, which is driven rapidly and with great force through the pipes over the valve and around the valve-rod, tends `to carry up the valve and valve-rod until the former is brought up firmly against its seat, at which time the pressure of the water in the pipe B, as well as in the chamber C, will hold the valve in such` position, tightly closing the entrance to the pipe A. Thus the pressure of the valve, when .not overbalanced bythe superior weight of the tumbler,will

,hold the valve always to'its seat. Under this arrangement, the weight of the valve and valve-rod must, of

course, bear a certain proportion. tothe pressure of the hea'd of water; This, however, can readily be determined, as will be understood withoutfurther explanation. l i

In connection with therapparatu's just described for washing the interior ofthe tumbler, I employ a device for'washing the exteriorof the same, consisting of one or more upright pipes E, which support and open into an annular pipe, F, provided with a series of .oriiices or holes, f, from which water is discharged directly upon the tumbler placed overthe pipe A. The lower ends of lthe tubes E open into the central pipe Av at a point -above where the valve 6 is located, so that, when the valve. is opened, water-will pass not only through the central pipe A, but also through the conduits E into the annular pipe F, whence it will be discharged in small streams or `iets through the oricesf upon the exterior` of the tumbler. Thus, by means of the one valve Z1, thc ow of water to all thepipes is regulated. At the points where the conduits E'open into the annular pipe F, set-screws or cocks g are inserted, by means of which more or less water may be admitted to the annular pipe, as may be desired. Instead of the annular pipe, a series of small upright tubes may be employed, attached to the pipe A, a's are the ,conduits E, and haviug their upper ends or nozzles turned in toward thetumbler, so that the water discharged therefrom will b'e projected directly upon the exterior of the tumbler. The oricesf in the annular pipe, or the nozzles of the smaller pipes just referred to, may be inclined or standing with respect to the tumbler, as indicated in iig. 1, so that the water discharged therefrom will strike ,the tumbler at an acute angle, or jtangentiall'y. By this means, if the head of water is at'allstrong, the tumbler will be caused to revolve rapidly upon the central pipeover which it is placed.

Having now described my invention, and the manner irl-which the same is or may be carried into effect, what I claim, and desire tosecure by'Letters Patent, is

l. .The combination, with the central pipe over which the tumbler is placed, of an annular pipe or a series of pipes for discharging water upon the exterior of the tumbler, and avalve-mechanism operated by the weight of the tumbler, so as to admit water to both the central and the exterior pipe or pipes, substantially as and for .the-purposes herein shown and'l set forth.

2. The arrangement of the nozzles or orioes through which water. is discharged upon the exterior of the tumbler in the manner described, so that the jets of water shall be discharged tangentially or thercabouts to the tumbler, substantially as and for the Vpurposes herein shown and set forth.

3. The combination, with the central pipe, of the annular or exterior pipe and adjusting-screws or equivalent mechanism forvregulating the pressure of water in the said pipe, substantially as and for the purposes herein Shown and specitied.

In testimony whereof, I have signed my nam'e to this specication before two subscribing witnesses.
